WIRE-DRAWING MACHINE.

Specification of Letters Patent.

Patented Nov. 15, 19-10.

Application filed ivrarch 5,1906. Serial No. 304,182.

Be it known that I, RALPH L. MORGAN, a citizen of the United States, residing at Worcester, in the county of Worcester and .(Jommonwealth of Massachusetts, have invented a new and useful Improvement in Wire-Drawing Machines, of which the following is a specification, accompanied bydrawings forming apart of the same, in

which- Figure 1 is a plan view of a wire drawing machine embodying my invention, and Fig.-

2 is a central sectional view of a wire draw: ing capstan.

Similar reference letters and figures refer to similar parts in the difle'rent views.

My invention relates to improvements in capstans for continuous wire drawing machines, whereby I prevent the removal of small particles of metal from the wire seat bythe friction of the wire, and the conse- Yqu'ent clogging of the dies by such particles,

and it consists inthe construction and arrangement of parts as hereinafter described. and pointed out in' the annexed claim.

Referring to the accompanying drawings 1 denotes the frame of the wire drawing machine. The pulley 2, journaled in the frame 1, is driven by suitable connection with the source of power, not shown, and the pulley 2 by means of the gears 3, 4E and 5 drives the shaft-s6 and 7. The wire 8 is drawn through. the dies a, Z) and 0 in the die box 9 by the capstan 10 on the shaft 6. Aftereach operation of drawing it passes beneath the die boxar'ound the scored idlers 11, 12, and 13 respectively, which change its direction and it is finally drawn through the die (if in the die box 9 by the drum 14: turning with the shaft 7.

The capstan 10, as shown in Fig. 2, is composed of disks 15, having between them annular wire seats 16. The wire seats 16 are composed of wood or other nonmetallic substance having elongated and flexible fibers of a character different from the granular par ticles of the wire, and are firmly held be tween the disks 15 by the nut 17 which draws the disks 15 together and against the shoulder 18 on the shaft 6. By thus makingthe wire seats 16 of a nonmetallic material I prevent the attrition oimetal on metal as '1 the wire passes over the wire seats, and the consequent erosion of minute particles of metal from the wire seats, which are liable to be carried by.the wire into the dies and tend to clog or obstruct the free passage of the wire through the dies. By making the wire seats of nonmetallic material of the character above described, however, the particles worn from them by the passage of the wire are fibrous or elongated in character and have a tendency to be removed from the wire when it enters the die. By thus varying the character and shape of the particles worn from the wire seats the dies are enabled to keep themselves clear and free of any foreign substance that would tend to retard the passage. of the wire.

I-claim,

A continuous wire drawing machine having said capstan.
